Fig. 7. In the absence of extrinsic cues, neuroblast cortical polarity does not form at the same position over multiple cell cycles. Series of still images from time-lapse confocal movies from a clustered (A) and an isolated (B) neuroblast dissociated from embryos ubiquitously expressing Dlg:eGFP. Mitotic stages and cell cycles are listed above each panel. White arrowheads indicate the center of the Dlg:eGFP crescent, most prominent at metaphase. White asterisks indicate the position of the newly born GMCs. Scale bar: 10 µm.
